Hello folks, this is the scenario:
I tried to run the following code in EasyEclipse for Ruby IDE and
SciTE on WinXP
Both has the same behavior.
def main
print "Enter the number of employees: "
numEmp = gets
puts "The number of employees is:= " + numEmp.to_s
end
main
====================
The output is nothing ( it appears that the program hangs-on for a
while ), then if go to the console and I push the ENTER key it appears
the "Enter the number of employees: " and suddenly the program
terminates.
What I’m doing wrong?, I tried to follow the instructions from several
books ( David Black’s “Ruby for Rails” and Dave T. “Programming
Ruby” ) and both indicates that the kind of code that I wrote should
work.
Any help would be very appreciated.
Regards

Have you, per chance, tried to invoke your script from the command line?
I know that SciTE needs to be patched in one way or another to allow for
input. I can’t judge Eclipse in that regard, as I don’t use it.

Yes I tried from within irb… and it works perfectly, however when I
use either SciTE or EasyEclipse the behavior is awkward.

Carlos -
I can’t speak to SciTE, but Eclipse (specifically with RDT) has an issue
with the syncing of input/output.
See the first question at
Aptana.com | Axway for information about
resolving the issue. Or just run from the command line.

That should help. 
Bjorn:
Thanks it worked great!
However is it possible you can explain me in general terms why this
behavior happens?
I mean, besides trying in EasyEclipse and SciTE I tried the same code
in irb, and surprisingly it works perfectly (no need to flush)!

Irb have Readline support and also automatically flushes everything -
just in
case :] by deafault print don’t flush - if you want flushing - use puts
